Product Details
✓The X-Series wideband UEGO AFR sensor controller gauge (PN 30-0300) features a modern, visually striking faceplate and new seven-segment, center display that is 87% larger than the 30-4110 AEM
✓The gauge includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging
✓X-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition
✓Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune
✓When tuning an engine using wideband AFR feedback control on an inertia dyno, dead time affects the data you are looking at because it is reported in a different operating location than when it actually occurred
